Description

Technical Field

[0001] The utility model relates to the technical field of double-sheet box gluers, in particular to a glue coating device of the double-sheet box gluer. Background Art

[0002] Carton gluer is a mechanical device used by carton factories to glue folding cartons. It is divided into two types: upper folding type and lower folding type. Carton gluer is generally composed of paper feeding part, deviation correction part, trace shaping part, gluing part, folding part, counting and discharging part. In general, carton gluer refers to equipment that completes the entire corrugated cardboard box-making process mechanically. When using carton gluer, it is necessary to glue the carton to facilitate box gluing.

[0003] According to the publication number CN218360385U, a gluing device of a carton gluer is used. When in use, the first motor is started to drive the first rotating rod to rotate, thereby driving the first threaded rod to rotate. The rotation of the first threaded rod will drive the threaded sleeve to move horizontally, thereby driving the guide frame and the guide roller to move. It can be adjusted according to the width of the carton to avoid the carton from shifting during the transmission process, thereby affecting the gluing effect. The second motor can be started to drive the second rotating rod to rotate, thereby driving the second threaded rod to rotate. The rotation of the second threaded rod will drive the moving block to rise and fall, thereby driving the bottom end of the glue outlet pipe to rise and fall through the connecting rod. It can be adjusted according to the height of the carton to make the gluing more accurate. After the adjustment is completed, the carton is moved to the bottom of the glue outlet pipe through the conveyor belt, and the control valve at the bottom of the glue outlet pipe is opened to glue the carton.

[0004] The bottom end of the rubber hose can be raised and lowered by the second threaded rod and the connecting rod to make gluing more accurate. However, when the carton gluer is used, the sizes of cartons to be glued are different, and the locations where the glue is applied are also different. The rubber hose is installed on the frame and is not easy to move, which reduces the practicality of the device. Utility Model Content
